Unlimited (most items)

Yes

Free

None

Not specifically extended (already unlimited)

Cigarettes, alcohol (where prohibited), gift cards, tickets, custom orders, precious metals, airline tickets

Costco's return policy is essentially unlimited for most items — there's no expiration date on your return window. You can bring back clothing, furniture, appliances, and most general merchandise months or even years after purchase. The main exceptions: electronics and appliances have a 90-day return window, and diamonds over one carat require the original GIA or IGI certificate. A handful of items can't be returned at all, including cigarettes, alcohol (where prohibited by law), gift cards, tickets, custom orders, precious metals, and airline tickets. For everything else, the clock never really runs out.

Yes — and this is one of the genuinely great things about shopping there. Costco's membership system logs every single purchase tied to your membership card, so a paper receipt is never required. Walk up to the returns desk, give them your membership number, and they can pull up your entire purchase history instantly. No digging through old emails or drawers. One heads-up for 2026: Costco has been tightening enforcement on members who return items too frequently, so don't treat the no-receipt policy as a loophole for habitual returns.

No, Costco does not charge any restocking fees. Whether you're returning a $30 blender or a $2,000 TV, you get your full purchase price back — no deductions, no penalties, no fine print. Return shipping on online orders is also free. This is one area where Costco genuinely outperforms most retailers, especially for big-ticket items like electronics and appliances where restocking fees of 15–25% are common elsewhere. Just keep the 90-day window in mind for electronics and appliances if you want to stay inside the standard policy.

Yes, Costco accepts returns on opened and used items for most product categories. The policy doesn't require items to be in original packaging or unused condition. If a vacuum stopped working after a few months, a mattress wasn't comfortable, or a piece of clothing didn't hold up — you can return it. The practical limit is the 90-day window for electronics and appliances; beyond that, opened or not, those returns won't be accepted under the standard policy. For everything else, "opened" is not a barrier. Just bring the item to the returns desk with your membership card.

Costco doesn't publish a specific holiday return extension — but it doesn't need to, because the base return policy is already unlimited for most items. A gift bought in October and returned in February is treated exactly the same as any other return. The one scenario to watch: electronics and appliances are still capped at 90 days regardless of the holidays. So if someone receives a laptop or tablet as a holiday gift in late December, that 90-day clock starts at purchase, not at the time the gift is opened. Plan accordingly if you're buying electronics as gifts.

Yes, most items purchased on Costco.com can be returned to any Costco warehouse location — you don't have to ship anything back. Bring the item and your membership card to the returns desk. For large or bulky items that are difficult to transport, Costco.com also offers free return pickup. The same product restrictions apply whether you bought online or in-store: electronics and appliances are 90 days, and the non-returnable categories (gift cards, alcohol where prohibited, etc.) are consistent across both channels. In-store returns are generally faster than initiating a mail return.

Costco does not publicly publish a dedicated military discount program. There is no standard percentage-off discount for active duty, veterans, or military families at the register. However, Costco does periodically offer discounted membership promotions that may be available to military members through specific partner channels or military base exchanges. The value proposition at Costco is already built around wholesale pricing rather than tiered discounts. If you're looking for a confirmed military discount, this policy is not publicly listed and your best option is to contact Costco member services directly or check base exchange partnerships.

Costco does not price match competitors like Amazon, Walmart, or Target. The warehouse model is built on negotiated bulk pricing rather than real-time price matching. However, Costco does offer a limited price adjustment for its own prices: if an item you purchased goes on sale at Costco within 30 days of your purchase, you can request a price adjustment at the returns desk. This applies to both warehouse and Costco.com purchases. That internal adjustment window is useful for catching Costco's own promotions after the fact, but don't expect them to match outside retailers.

Returning a Costco gift without a receipt depends on whether the giver used their membership card for the purchase. If they did, the transaction is in Costco's system and a membership lookup at the returns desk can locate the order — though the refund typically goes back to the original purchaser's payment method or membership account. You'll want to coordinate with the gift-giver for this. If the gift was purchased using someone else's card and they can't assist, the return process becomes harder since Costco ties purchases to membership accounts. In-store store credit may be an option — confirm with your local warehouse.

Defective items follow the same return process as any other return at Costco — bring it to the returns desk with your membership card, no receipt required. For most product categories, there's no time limit, so a defective item discovered a year later is still returnable. For electronics and appliances, you're within the 90-day window for a direct return; after that, Costco may direct you to the manufacturer's warranty process instead. For large items purchased online, free return pickup is available. There's no restocking fee and no requirement to prove the defect with documentation — member purchase history handles the lookup.
